ME'H'IQD OF AND MACHINE FOR FITTING HEELS TO THE SOLES OF SHOES Filed March 23, 1929 4 Sheets-Sheet 4 'Patented Mar. 1, 1932 UNITED STATES PATENT OFFICE GEORGE nhznm'on AND when axons, or Lsiciisrnn, ENGLAND, AssIGNons TO UNITED snon maonmnay oonrom'rxon, or PATERSON, NEW JERSEY, a coaronmzon or NEWJERSEY METHOD OF'AND nhuman son FITTING HEELS TO THE SOLES or" sHoEs Application tiled March 23, 1929, Serial No. 349,443, and in Great Britaln'llarch 29, 1928 This invention relates to methods of and mach nes for manufacturing shoes and 1s herein illustrated as embodied in a machine adapted to fit the heel-seat portions of shoes forthe reception of-Louis' heels and to trim Louis heels for reception by the hoel-seat portions of shoes.

A typical Louis heel has a lip extending transversely of the heel from one side of the heel to the other at the top portion of its breast, the front ed e of the lip tapering substantially-to a feather edge in order that the heel will blend properly with the shank portion of the shoe Where it joins the latter.

In the manufacture of shoes having wooden Louis heels it is the practice to apply the heel, after it has'beencovered, to the sole of the shoe which sole already has been split at its rear portion to form a breast fiapfor covering thebreast of the heel. 1 r i v w In fitting a Louis heelto a shoe the sole of the shoe is usually trimmed'at its rear por tion to form a reduced heel-seat portion for reoeivin .thecupped attachin face of the heelan to fol-ma pairof heel reast receiving houlders extending laterally ofthe sole fronnthe reduced heeIseat" portionv substantially atthe heel-.breastiineof the sole;

In order to. form a neat joint where the lip df -theheel rests upon the shank portion of thesole, over which joint the breastl'fla "of the; sole should=lie smoothly and wit out bul 'ng, the heel breast receiving shoulders of t is soleand the-end portions of the :feather V edgeof the heel breast should be of substantiallycthe same size and complements of each other. Since the abutting endsof the feather edge as commonly made have no'substantial" surface areas the heel breast receiving shoulders which usuall extend transversely of the sole are necessari y of smallsurfacc'area and do not serve as satisfactory abutmcnts against which to position the heel.

A shoe provided with a Louis heel and having a neat joint where the lip of the heel and the shank ortion of the sole are joined but having sur aces or heel breast receiving shoulders of=substantial area at the breast line of the sole is disclosed in application Se rial No. 319,589, filed November 15,1928, in

jecting lip with a feather edge,at each end of which is a shoulder having a substantial surface area positioned at a substantial angle to the feather edge.- These shouldersare constructed and arranged to abut against the corresponding heel breast receiving shoulders formed upon the sole of the shoe;

An object of this invention is to provide a machine for, trimming a Louis heel having a projecting lip with a feather edge to form shoulders of substantialsurfaceareas at the ends of the feather edge. 7

Another object of this invention isto rovide a machine for trimming a Louis eeland the sole of a shoe in such a manner that the trimmed heel will have-portions formed thereon which are complemental to ortions formed upon the sole in order to ac ilitate the accurate positioning of the'heel upon the sole for registry therewith. 1 i i With, theabovestated objects in View a nin accordance with a featurejof theinventioni:

tions in the machine so that'when trimmed th y will correctly mate with one another, the

illustrated machine is provided with members for receivingthe sole of "a shoe, mem

here for receivinga heel, and mechanism controlled b the heel for determining the position of t e sole in thesole receiving means.

To position the heel correctl in the machine while it is being trimm and in accordance with another feature of the invention, the illustrated machine is provided with means for positioning the heel in the machine widthwise of theheel before it is positioned lengthwise of the heehand means for normally urging the ositionin means into contact with the bee and for. ocking the tioning means against movement away the heeL lift,

A further feature of the present invention comprises novel means for trimming a Louis heel having a protruding portion terminating in a feather edge, which heel has been positioned in the machine as above described.

"iechmismiforleeaflne e d'i le* trimmed in the machine embodiedin the present inventions-rid arranged to-litthe preaches the attaching face, forming a lip portion 42 having, as viewed from the sides of the heel, a somewhat wcdge'shape. The forward part of the ii i is thinned toe feather edge 44 which extends from one side of the heel to the other and which'is adapted to conform to the surface of the shank portion 46 of. the sole 48 of the shoe. As is usual in shoes having Louis heels, the sole is s lit to provide a breast flap 50 which is app led to the breast of the heel.

In the fitting of a Lou-isheel to a sole it is necessary that the feather edge 44 of the lip portion 42 shall fit snugly upon the median portion of the sole of the shoe, in order that the breast flap 50, which is applied to the breast of a heel, shall blend properly with the sole where it'lies over the feather edge 44 of the heel. If for any reason the feather edge does not sent properly upon the sole, there will be a bulge in the surface of the sole at the portion indicated at 52 (Fig. 2) where the feather edge -l4mects the shpnk portion of the sole, which bulgespoils-tlie appearance of the shoe. v k

The heel 34 is trimmed in applicants machine by truncating its corners 54 which are formed between the breast edges 56, the feather edge 44 and the-rim portion 58 of the attachlng face to form the surfaces or shoulders 60 which are constructed and arranged to engage complemental heel breast receiving shoulders 62 formed on the sole of the shoe; which heel breast receiving shoulders are preferably undercut heightwise of the sole. as indicated by reference character 64, and extend from the reduced heel-seat portion .30 of the sole substantially at the heel breast line 66 rearwardly and laterally of the shoe.

The shoes shown in Figs. 1 and 5 have their sole attaching stitching 68 extending along the shank portion 46 of the shoe to points somewhat rearward of the breast line 66 of, The heel-seats which are formed;

the sole. by applicants machine are of full thickness throughout a substantial portion of their width and includesteeply beveled portions 70 extending along their margins in a di rection substantially lengthwise of the shoe.

By utilizing a wide reduced heel-seat portion 30 of'a sole having steepbe'vls 176, it is possible to produce a shoe having a sole with its line of stitching 68 uncut rearwardly of the breast line 66. which results in an improved heel-seat.

The sole 48 of Fig. 1 is what is termed a short sole, and accordingly its rear end 74 does not require trimming. This sole has been trimmed along its marginal portions 72 lengthwise'of the shoe in applicants machine to form the beveled portions 70. The

sole shown in Fig. 5 has been given a preliminary heel-seat trimming in another machine prior to its attachment to the shoe in Fig. 4, along its rear portion 16 as well as its rear side portions 78 to form a tapered tongue portion 86 (Fig. 5-) extendin from the lines 82 rearwardly of the sole, t e two soles being of the sole.

The breast of the heel illustated in Fig. 3 is provided with a forwardl extending projection adjacent to the attac in face of the heel. This projection is provi ed with 3 a feather edge 44 extending over a ortion of the'width of the heel and shoul ers 60, forming a substantial angle with the feather edge at the ends.84 of the feather edge and extendin rearwardly of the heel as well as 85 toward t e sides 36 of the heel, said shoul- -ders 60 also extending forward of the heel its they approach the attaching face of the loci.

The shoulders 60 may be'said to be formed by a pair of substantially plane surfaces each defined by two lines 86 and 88 intersectin at points 90 on the breast ed e of the bee the line 86 extending forwarr ly of the heel and toward the center of the feather edge 44 from the point 90 and the other line 88 extending forward] of the heel and toward theheel attaching ace, said planes truncating the corners 54 of the heel.

The heel breast receiving shoulders62 of the sole of the shoe extend laterallyand rearwardly of the solo from the marginal portions 70 of the reduced heel-seat portion of the sole, said shoulders be inning at the points 92 substantially at the breast line 66 of 106 the sole and being undercut at 64 (Fi s; 1, 2 and 5). The breast receiving shoul ers 62 may be said to'be formed by a air of substantially plane surfaces each de 'ned by two lines 61, 63 (Figs. 1 and 5) intersecting at a 110 point 65 on the tread surface of the sole rearwardly of the breast line 66 of the sole and at the lateral edge of the sole, one of the lines extending forwardly of the'sole and toward the center of the breast line 66 of the sole and the other line extending forwardly of the sole and toward the attachin face of the sole.

The heel thus forme is adapted to be r e-. ceived by the heel-seat portion of the shoe so that the heel-seat lies snuglyin the cupped 159 attaching face of the heel, the shoulders 60 abutting against and mating with the heel breast receiving shoulders 62 and the feather edge 44 resting upon the median portion 46 of the sole at the breast line 66. range-ment of parts produces a shoe having at the meeting of the heel-seat and the base of the flap a union of parts that is smooth and graduated and gives a neat finish to the shoe.

as shown.

The machine as a whole, includes three prin-- cipal groups of instrumentalities:carried by; a lower head 102 (Figs. 6 and S), a middle 1 head 104 and a top'head 106, respectively. Thelowcr head 102 carries the shoe supporting means and formsa base forthe middle head 104 and the top head 106. The middle head 104 carries the sole trimming 411001151- nism and the actuating mechanism therefor while the top head 106 carries the heel clamping means for positioning and locking the heel in the machine. f I

The lower head 102 carries a forwardly extending horizontal bracket 108 having a T- shaped horizontal guideway 110 extendingi forwardlv and rearwardly of-the-machine. Slidingly mounted in the guideway 110 is a work support 112. (Fig. 6) haying a T-shaped base 114 (Fig. 8) slidingly mounted in the guideway 11050 that a shoe mounted thereon may be movedinto and out of position'to be trimmed. The work support also comprises' a vertically extending, portion 116 bored as shown at 118 to receive a post 120 having a slot 122 extending in the direction of its length and containing a pin 124 which is supported by the vertically extending portion 116 of the work support. The upperend of the post 120 is provided with a threaded recess 126 which receives thethreaded shank portion 128 of a shoe supporting. plate 130 (Figs.6 and 9) fixed in adjustedposition relatively to the post 120 by a nut 132 upon the shank. portion of the shoe supporting plate 130., A spring 134 is located within the recess 126 of the post 120, the ends of which spring engage against the pin 124and the lower end 136 of the shank portion 128 of the shoe supporting plate 180, normally to hold thepost 120in tie raised positionshown inFig. 6.

As will later be brought out, when the sole of the shoe is being trimmed the post 120 is in lowered position relatively to thevertically extending portion 116 of the work support, as

, shown in Fig. 9. In order-ate raise the post 120 for fixedly positioning the shoe to be trimmed, an arm 138 (Figs. (Land 9) pivoted for movement about a pm 140 mounted in the forwardly extending horizontal bracket 108 is raised upwardly through a slot 142 (Fig. 7) in the bracket 108 and a slot 144 in the work support 112 into contact with the The forward end of the arm 188 is normally held down by a heavy spring 148 which is connected to the arm at its forward portion 150. Pivoted about the pin [40 is also a forwardly extending dog 152 which is carried with but movable relatively to the arm 138 by a sprin 154, the dog being arranged to engage a rac 156 at the under part of the work support 112 to hold the work support from sliding forwardly of the machine when the shoe is having its heel-seat fitted.

The rear portion 158 (Fig. 6) of the arm 1 and 8) for supporting a forwardly wardly extending driving shaft 14 138 is connected by a link 160 to one end (if a pivoted to a plunger 164 which through associated mechanism hereinafter described operates a pair of crease plates 166 arranged to.

enter the rand crease of the shoe as far as the line of stitching 68 between the shoe upper and the sole. The floating lever 162 is connected at its central portion to a rod 168 (Fig.

. 6) extending downwardly to a treadle 172.

The middle head 104 is provided with bearings one of' which is shown at 174 (Figs. '6 and rear- 6. A cam 178 having cam rooves 180, 182 is mounted ,upon the shaft 1(6 to actuate throu h other mechanism, later to be described, eveling knives 184 which are moved lcn hwise of the sole to form the portions o the heel-seat portion of the sole sole shguldering knives 186 which are moved transversely and forwardly of the sole to form the heel breast reeeiving shoulders 62, and heel shouldering knives 187 (Figs. 7 and 8) which form the shoulders 60 upon the Louis heel above described.

The middle head 104 has on each side thereof and extendin laterally therefrom a pair of brackets 188 ig. 7) spaced fromone another, each pair providing a guideway 190 extending parallel to the front of the machine and slidingly supporting and guiding two laterally movable sliding beds 192, the guideways on opposite sides of the machine being in the same horizontal plane and in line with one another.

Since the sliding beds 192 with their associated parts are the same on both sides of the machine, it will be necessary to describe but one side, it being understood that the.

parts described are duplicated upon the opposite side of the machine. Each of the sliding beds 192 carries one of the sole shoulder ing knives 186, one of the beveling knives 184 and one of the crease plates 166, and upon the under side of each of said slidin beds there is a boss 194 (Fig. 8) in which is xed :1 depending stub 196, the lower end of which is pivoted at 198 to the outer end of a link 200, the other end of the link being connected at 202 to the plunger 164 which is mounted for vertical movement in a bearing 204 in the lower head 102 of the machine. The lower end of the plunger 164 (Fig. 6) is connected to the floating lever 162 already described, the mechanism being constructed and arranged so that downward pull on the plunger rod will move the kliding beds 192 toward one another in theguideways 190 in the middle head 104 of the machine.

The lower end of the plunger rod 164 (Fig. 6) has a lug 206 extending forwardly therefrom, which lug is provided with a hook 208 for receiving the end of a spring 210 the other end of which spring is connected to the lower head 102, the spring serving to keep the plunger rod 164 in a raised position which results in normally holding the sliding beds 192 at their extreme ositions away from one another in the guid ways 190.

The illustrated machine is also provided with'a holddown claznp 212 which serves to engage the attaching face of the sole of the shoe between the beveling knives 184 (Fig. 10) while thesole'is being trimmed in order to assist in tightly securing the sole against movement during the trimming operation.

The holddown clamp is ivoted at214 (F ig. 6) to the top head 106 t ough an arm 216 which is connected near its central portion 218 to a downwardly extending clamp actuating rod 220 passing through the forwardly I draw the sliding beds 192 and their crease plates 166 together it will depress the rod 220 and cause the holddown clamp 212 to engage the tread surface ofthe sole of a shoe asshown in Fig. 9. A turn buckle 228 upon the rod 220 may be used for varying the amount of pressure with which the clamp will engage the sole of the shoe and the time at which such engagement will occur.

The crease plates 166, which are located at the forward inner corners of the sliding beds 192 and which assist in maintaining the sole in position to be trimmed above their level (Fig. 9), are strong enough to-resist the upward pressure of .the work support post 120 and include thin finger portions 230 (Fig. 12) constructed and arranged to enter between the shoe upper and the sole at the .sidesoi the heel-seat portion of the-shoe. The upper surfaces of the crease plates 186 are provided with knife guideways 232 (Figs.-

7 and 12)- for receiving the bowling-knives 184, said guideways being formed by the shoulders 234 extending lengthwise of the plates and the fiat surface portions 236 (Figs.

8, and 12) which also extend lengthwise of the plates. The 'beveling lmives 184 are arranged to move in the guideways 232 along the angled portions of the crease plates formed by the shoulders 234 and the flat surface portions 236. The sliding beds 192 may be attached to the crease plates in any convenient manner such as that shown in Figs. 8 and 12 in which each plate includwa ton ue portion 240-and two tlireaded'bolts242 which may be fastened to the inner side 244 (Fig. 8) of the sliding beds 192.

Each sliding bed 192 is provided near its front margin with a guideway 246 (Fig. '7) which extends laterally and forwardly of the machine, the inner end of the guideway adjacent to the crease plates 166 being forward of the machine relative to the outer end of the guidewey. A knife carrier slide 248 is mounted for reciprocation in each guidewa 246 and has fixed to it a downwardly exten.

ing rod 249 (Fig. 8) which is adgusteblelengthwise of the slide in a. slot 250 Fig. 7,) by means of a nut 252 threaded upon the upper portion of the rod 249 so that the slide 248 may be initially adjusted in its guideway 246. the downwardly extending rod 249 re taming a fixed position with respect to the knife carrier slide 248 during the operation of the machine.

The lower portion of each downwardly extending rod 249 passes through a. bifurcated portion 256- (Fig. 7) of an am 258 having a. sleeve portion 260 (Fig. 8 mounted for turning movement upon the e ending stub shaft .196 attached to the sliding bed 192. Mounted on each sleeve portion 260 is another arm 262 extending laterally of the machine the end of which is pivoted to a link 264 Fig. 8) extending rearwardly of the machine and pivoted to a cross-head 266 (Fig.

6) which is attached to a. slider 268 con structed and arranged to slide forwardly and rearwardly of the machine in a guideway 270 Figs. 6 and 8) in the frame of the machine,

t e slider 2-68 carrying an upwardly extend ing roller 272 positioned in the groove 180 .of the cam 178." It will be clear that as the cam 178 is re- ,tated and the cross-head 266 is moved forwardly and rearw ardly of the machine the knife carrier slides 248 will be moved laterally and forwardly of the machine on the sliding beds 192. Since the connecting links 264 are of considerable length, movement of the sliding beds toward and away from' oneanother does not effect, to any harmful extent, the positions of the knife car- :i'ger slides 248 relatively to the sliding beds 2. i y The knife carrier slides 248 are'each provided with an upwardly extending lug 274 having a cylindrical recess 276 (Fig. 8) with its axis parallel with the directionof movement of theknife carrying slides 248. A knife carrier 278 has a cylindrical shank portion 286 received by the'cylindrical recessed port-ion276 of each upwardl extending lug 274 and is held in place t erein a bolt 282 (Fig: 7 and 8) 'passingthrougli the cylindrical red portion. The nife car- :rier 278 isalso provided with a portion 284 ext-ending forwardly and downwardly of the machine and provided with a T-shaped groove 286 (Fig. 7) forre'ceiving the thin flat knife 186 and a clamping plate 290, T-

shaped in cross-section, which plate is inserted in the T-shaped groove forward of the knife 186, the knife eing held in pos1- tion in the knife carrier (by a screw 292 Figs; 7 and 11) passing through the'T- s aped clamping plate 290, the knife 186 and entering the rear face 291 of the forwardly extending portion of theknife can rier so that the thin flat knife may be clamped between the bottom of the groove 286 and the clamping plate 290.

The construction and arrangement of the parts above described is such that in operative position (Figs. 6 and 7 the knife 186 extends downwardly and forwardly of the machine at a steep inclination to the horizontal, the plane in which the blade lies be ing arallel with the line .of movement of the nife carrier slide 248. With such an arrangement of parts it is thus clear that the heel breast receiving shoulders 62 formed at the forward portion of the heel-seat will extend laterally and rearwardly of. the sole and have an undercut 64 widthwise of the solo.

The lower cutting edge 296 (Fig. 11) of the shouldering knives 186 are arranged at right an les to the sides of their respective knives and are higher at their inner corners than at their outer corners in order to form an angle with and transversely of the attaching face of the sole. 1

Each of the cutting edges 296 (Fig. 11) of the shouldering knives 186 is arranged substantially at the same inclination to the attaching face of the solo transversely of the sole as the cutting edge of its corresponding beveling knife 184 so as to form a cleancut shoulder at 91 (Figs. 1 and 5) the shouldaring and beveling knives being arranged so as not to appreciably cross thepaths of one another. 7

Each of the s'houldering knives 186 (Fig. 10) moves along the front edge 304 (Fig. 7 of the crease plate 166,. which front edge is parallel to the line of the movement of the knife carrier slide 248, the knife thus being supported against rearward springing by the crease plate and forming a shearing couple therewith.

In order to support and guide the beveling knives 184, each of the sliding beds 192 has a raised portion 306 (Fig. 8) the under side of which has a horizontal dovetail guideway 308 which extends forwardly and rearwardly of the machine and in which a knife carrier 310 (Figs. 8 and 12) is mounted for movement. The upper surfaces at the rear ends of the knife carriers 310 (Figs. 6, 7 and 12) are provided with transverse slots 312 for receiving a cross-head 314 which is constructed and arranged simultaneously to actuate both knives and to allow the knife carriers 310 to be moved toward and away from one another with the sliding beds 192, with out causing any relative movement in a direction lengthwise of the knife carriers 310 between the-sliding beds 192 and the knife carriers;

The cross-head 314 is integral with a dovetail slider 316 which is arranged to slide forwardly and rearwardly of the machine in a horizontal slideway 320 (Fig. 6) formed in the bottom portion of the top head 106, the dovetail slider 316carrying a depending cam roll 318 that engages the 'cam groove. 182 in the cam 1T8. Uon rotation of the cam 178 the dovetail slit er 316, through the crosshead 314, moves the knife carriers 310 forwardly and rearwardly of the inachine'to bevel the marginal portions of the heel portion of the sole in a direction extending substantially lengthwise of the shoe.

The under surface of each knife carrier 310, along its inner margin 322 (Fig. 12), is beveled to slope upwardly and toward t 1e longitudinal axis ofthe machine at a steep angle to a-horizontal plane. 7 The knife 184 having an elongated portion with a beveled cutting edge 324 and a fla'nged portion 328 is fixed to the front face 326 of the knife carrier 310 by means. of the flange 328 which is screwed against the said front face 326 of the knife carrier, the knife thus extending forwardly of the knife carrier and having its beveled edge 324 extending laterally of and forming a substantial angle with the flat surface por: tions 236 of the crease plates and the attaching face of the sole. It will be noted that the angle which the cutting edge "of the knife makes with the surface of the sole may be changed as desired, such change being brought about by attaching knives of different angles to the knife carrying slides.

Since the knives 184 travel in the knife guideways 232 with their cutting edges 324 inclined at an angle to the crease. plates-166, and their corners 330 moving along the shoulders of the crease plates (Fig. 12); it will be clear that the finger portions 230 of the crease plates 166will extend far enough between the sole of the shoe and the shoe upper to protect the upper from being cut'by the knives, and the knives will be prevented-from springing relatively'to the plate as they trim the lateral marginal portions of the sole. 7

The shaft for rotating the cam 178 is actuated by a one-revolution clutch 332 mounted at the rear of the machine and is thrown into operation by the hand lever 334 (Fig. 8).

In order to position the shoe lengt wise in the machine so that the beveling knives and the shouldering knives vwill operate at correct positions on the sole to form a reduced heel-seat portion of such length that the heelbreast receiving shoulders 62 which are the complements of the heel shoulders 60 will register with the heel shoulders correctly to position the heel upon the sole of the shoe, mechanism is provided whereby rearward move ment of the shoe to be operated upon is halted by contact of the rear portion of the shoe upper against a back gage 382 (Fig. 6) having a concaved front face 384, the position of the back gage being determined by a heel clamp or heel-clamping mechanism 385 constructed and arranged to receive the heel to be trimmed heel-attaching face down and heel breast toward the front of the machine as shown in Figs. 6 and 8. The back gage 382 is slidable forwardly and rearwardly of the machine in a guideway 388 (Fig. in the middle head ml.

The top head 106 carries the heel clamp and connecting mechanism for regulating the position of the back gage 382. The back gage 382 has rigidly fixed thereto an upwardly extending post 390 (Fig. 6) having its upper end connected to a traveler 392 which slides forwardly and rearwardly of the machine in a guideway 39- An upstanding post- 396 is connected to the traveler 392 and is provided with a threaded hole 398 extending parallel to the length of the slider and receiving a screw 460 having a knurled head 402 at its rear end. The front end of the screw 400 is provided with a collar +l0-l that lies in a recess 406 (Fig. 7) in the rear gage plate or abutment 408 which has a curved recessed portion 410 (Figs. 6 and 7) for engaging the rear marginal rim portion of the heel.

The front portion of the top head 106 carries a breast gage or abutment -ll'2 arranged to engage the feather edge 44 of the 4 projecting lip 49 of the heel (Fig. 6), the

gage being mounted for movement forwardly and rcarwardly of the machine in a guideway 416 (Fig. 7) for initial adjustment of the gage to accommodate different sizes and shapes of heels. The initial adjustment of the gage is effected by means of a screw 418 (Fig. 6) which passes through an upstanding threaded recess in a flanged portion of the breast gage. the screw being mounted for rotation in the lug 422 of the top head.

The top head 106 is also provided (Fig. 7) with a pair of horizontal guideways 426 (Fig. 7) extending toward the longitudinal center of the machine and forwardly of the machine. In order to engage the sides of the heel for centering the same in the machine, clamp slides 430 are arranged for reciprocation in the guideways 426. each clamp slide carrying clamping members 432 connected to the clamp slides 430 by screws. The heel contacting ends of the clamps 432 (Fig. 8) are inclined upwardly and toward one another at an angle of about degrees to the hori' zontal and preferably carry clamp pieces 4-3.. of rubber or leather in order that they will not damage the covering on the heel.

Projecting downwardly from the clamp slides 430 are pivot pins M0 connected by links 442 to other pivot pins H4 (Figs. 6 and 7) that project upwardly from a heel clamp actuator 446 (Fig. 6) the arrangement and positions of the parts being such that when the clamp slides 436 are in their outcrinost position the links 142 will appear as a straightened toggle and when the clamp slides are in their innermost position the links appear as a broken toggle as shown in Fig. 7.

The under surface of the rear gage plate 403 (Fig. 6) and the upper surface of the heel clamp actuator 446 are provided with racks 418, 450 respectively, which engage a pinion 452 carried by a compensating block +154, slidable in the guideway 456 in the top head 105 of the machine. 454 is operated by a pin 458 (Figs. 6 and T) extending from one side thereof, the pin being received by a bifurcated portion 460 of an upwardly extending arm (Fig. 7) which is fixed upon a rock shaft 464. mounted for rotation in a bearing 465 supported by the middle head 104.

The clamping members 432 are mounted for movement with the back "age or abutment 408 through the pinion 402 carried by the compensating block 454 and are arranged to engage the heel laterally to position the heel. widthwise of the heel in the machine before the heel is positioned lengthwise of the heel in the machine. when the heel is substantially in its proper lateral position to be trimmed in the heel clamp the back gage or abutment 408 is arranged to engage the heel to move the same to its proper position lengthwise of the heel to be trimmed.

Clamping of the heel in this manner thus not only positions the heel to be operated upon by the heel-trimming means, which will be described later, but also automatically posi tions the back gage 382 so that the sole of the shoe will be properly positioned lengthwise of the shoe in the machine to have its heol-- seat and heel breast receiving shoulders ar ranged to facilitate the correct positioning of the heel upon the sole.

Provision is also made for normally urging the heel clamp in contact with the heel and for urging the back gage forwardly of the machine. Means is also provided for lock ing the back gage against rearward movement under pressure of the shoe, the locking means being constructed and arranged to hold the back gage in its foremost position against the shoe upper and to hold the heel clamp against theheel.

Keyed to the outer end of the rock shaft 464: is a hub 466 (Fig. 13) carrying an upright arm 468 having a yoke portion 470 (Figs. 13 and 14) in which is mounted a. pawl pin 472. Extending axially from the huh 466 are av pair 11f projecting lugs 47-1 which are arranged to be engaged by a. pair of ax ially extending lugs 476 upon a lever 478 loosely mounted upon the rock shaft 464. A treadle rod 480 pivoted to the lever 478 and forwardly extending from said lever 478 is an arm 4 carrying a spring .18 tfor bolding the arm 18:? normally in a downward position. Clockwise movement of the arm 482 through mechanism carried by the yoke 476,

The compensating block i which mechanism will be later described, causes the upright arm 468 to move in a clockwise direction (Fig. 14), thereby moving the compensating block 154 forwardly of the machine. Conversely upon depressing the treadlc rod 480 the lugs 4T6 abut against the lugs 474 rotating the upri ht arm 468 in a. counterclockwise direction t iereby moving the compensating block 454 rearwardly of the machine, the compensating block carrying with it the pinion 452 which engages the rear gage plate or abutment 408 and the heel clamp actuator 446 to more these two parts rearwardly of the machine. Rearward movement of the heel clamp actuator 446 causes the clamps 432 to move away from one an other by reason of the toggle action of the links 442. The heel clamp is thus'opened to permit a new heel to be inserted, which heel is placed with its attaching face downwardly upon the top surface 486 of the heel support ing plate (Fig. 6) and with its breast 40 resting against the breast gage or abutment 412. Upon the release of the treadle rod 480 the spring 484 through the upright arm 46S and mechanism carried thereby, which will later be described, causes the compensating block 454 to move forwardly of the machine carrying with it the rear gage plate or abutment 408 and heel clamp tctuator 446. Should the clamps 432 come to a stop after laterally positioning the heel to be trimmed before the rear gage plate 408 has completed its function of lengthwise positioning of the heel in the heel clamp, the compensating block 454 will continue to move forwardly, the pinion 452 rolling upon the ratchet teeth 450 of the heel clamp actuator and urging the rear gage plate 408 forwardly of the machine until it has positioned the heel to be trimmed lengthwise of the heel, at which time forward mo cment of the compensating block ceases, the heel being held in position by the treadle spring 484.

A convenient form of locking mechanism for the heel clamp and the back gage 382 cmbodies a. device which locks the back gage against movement rearwardly of the machine as well as locks the heel clamp for holding the heel securely in position to be trimmed.

The locking mechanism comprises a ratchet disk 490 mounted on the frame of the machine and engaged by a depending pawl 499. mounted upon an eccentric sleeve 494 carried by the pawl pin 472 and provided with a pawl spring 496 (Fig. 11) fastened in the yoke 470 for urging the pawl into en gagcmcnt with the ratchet disk 490. The eccentric sleeve 494 has a laterally depending arm which will be referred to as the eccentric actuator 498 and projecting forwardly of the machine from the eccentric actuator is an arm 500 connected by a spring 562 to the arm 482, the arrangement of part being such that the eccentric actuator 498 is normally in rcction.

a substantially upright position (Fig. 14) during the trimming operation of the machine.

The lever 478 which is free to rock on the shaft 464 and carries projecting lugs 476 arranged to engage the lugs 474 of the hub 466 is provided with an upstanding car 504 which is arranged to engage a laterally extending portion 506 of the pawl 492 so as to rock the pawl in a clockwise direction to raise the pawl 492 from the ratchet disk 400 prior to the time that the lugs 476 of the lever 4T8 engage the lugs 474 of the hub 466. Upon depression of the treadle rod 480 the upstandmg car 504 moves in a counterclockwise direction, as viewed in Fig. 14, and lifts the pawl 492 from engagement with the ratchet disk 490. Upon further depression of the treadlc rod, the lugs 476 on the lever 478 engage the lugs 474 of the hub 466 and rock the 11 right arm 468 in a counterclockwise direction (Fig. 14) carrying with it the rock shaft 464 which moves the compensating block 454 rearwardly of the machine, thereby moving the back gage rearwardly of the machine and opening the heel clamp for the removal of the heel. A new heel is then in sorted in the heel clamp and the pressure of the trcadle is released allowing the spring 484 to move the lever 478 in a clockwise di- As the lever moves in a clockwise direction, its upstanding car 504 engages the eccentric actuator 498 to throw the pawl 49:! against the ratchet disk 490 and to rock the u standing arm 468 in a clockwise direction ig. 14). Since the upstanding arm 468 is actuated in a clockwise direction through contact of the upstanding ear 504 of the lever 478 with the eccentric actuator 498, the pawl 492 will at all times be pressed down'npon the ratchet disk to prevent backlash, the parts of the mechanism thus being held against backward movement.

The heel trimming mechanism for operating upon 21 Louis heel to form shoulders 60 which are complements of and are constructed and arranged to register with the heel breast receiving shoulders will next be described. The top head 106 at its upper surface is provided with a pair of horizontal guideways 510 (Fig. 7) extending laterally and slightly forwardly of the machine and parallel with the guideways 246 of the sole shouldering knives 186. A knife carrier slide 512 is positioned for rectilinear movement in each of the guideways 510 and has one of the heel shouldering knives 187 mounted upon its forward end 514 (Fig. by means of a clamping plate 516 and screw .318 such as are used in securing the sole shouldering knives 186 to their knife carriers.

The cutting edge 520 of the knife 18? as observed from the front of the machine (Fig. 8) lies in a vertical plane and .i v ewed from the side of the machine a ti lit plane extending upwardly and rearwardly of the machine from the surface of a heel supporting plate 522 at a suitable angle for forming the shoulders 60 on the heel. The heel supporting plate 522 is provided with a shoulder 52-1 (Figs. (3, 7 and 8) at its forward portion along which shoulder the knife 187 is arranged to move in order to support the knife against rearward springing.

Each of the knife carrier slides 512 is reciprocatcd through a rod 526 (Fig. 8) passing through the slide and extending downwardly therefrom, which rod may be clamped to the carrier slide when t has been positioned and adjusted as outlined in connection with the knife carrying slides 248.

The lower portion of the rod 526 (Fig. 7) is embraced by a bifurcated portion 528 of the arm 530 extending forwardly and rearward 1 of the machine and pirotally mounted upon the pin 532 carried by the top head 106. An inwardly extending arm 531 rigidly connected to the arm 530 has itsrear end pivoted to the front end of a forwardly and rearwardly extending link 531 (Figs; T and 12) the rear end of which is pivoted at (Fig. 12) to the laterally extending cross head 314 which has been described. The heel shouldering knives 187 at opposite sides of the machine will form shoulders on the heel simultaneously since they are both connected to the cross head 314.

In carrying out. the heel-seat fitting and heel trimming operation the operator depresses the trcadle rod 180 to open the heel clamp and places a covered heel in said heel clamp with the attaching surface of the heel against the heel supporting plate 522 and the breast of the heel engaging the breast gage or abutment 412 which has been initially adjusted. The treadle rod 480 is then released whereupon the clamps 432 move inwardly from the sides of the heel and the rear gage plate 408 moves forwardly ofthe machine to position the heel in the machine and to lock the heel thereon, the back gage at the same time being automatically moved'forwardly of the machine for positioning the sole attached to the shoe upper in the machine lengthwise of the shoe.

The operator next places the inverted shoe upon the shoe supporting plate 130 with its heel end toward the machine and slides the work support 112 rearwardly until the rear end of the shoe engages with and is stopped by the back gage 382, the shoe supporting plate 130 being depressed by hand against the pressure of spring 136 as the support is slid rearwardly so that the thin linger portions 230 of the crease plates 166 may enter the crease between the shoe upper and the sole.

The treadlc 172 is then depressed causing the sliding beds 192 to be moved toward one another and causing the crease plates 166 furthcr to enter the crease between the shoe uper and the sole. As the treadle 172 is still urther depressed the post 120 is moved upwardly and as the treadle 172 comes near the bottom of its stroke the holddown clamp 212 is brought into operative position upon the attaching face of the sole of the shoe Fig. 9) the crease plates continuing to enter IOtWBQIl the shoe upper and the sole until they are stopped by the line of stitching (58. During the heel-seat litting operation the treadle 172 is kept depressed to hold the parts in their relative positions, the sole being substantially flat with its marginal portions undistorted by the entrance of the crease plates. When the shoe has thus been placed in operating position the operator next depresses the hand lever 334 which allows the one-revolution clutch 332 to rotate the cam 178 a single revolution, to operate the sole beveL ing knives 184, the sole shouldering knives 186 and the heel shouldering knives 187. When the various cutting operations have been coliipleted the machine is automatically:

declutched and comes to rest. customary to make the beveling cuts and to form the shoulders on the heel before the sole shoulder cuts but the order of operation of the knives may be changed if desired.

When the pressure on the treadle 172 is released the sliding beds 192 are automatically mowed away from one another and the holddown clamp 212 is automatically raised from the sole of the shoe. Finally the work support 112 which is now unlocked is moved away from the machine to remove the shoe and the treadle rod 480 is de ressed to remove the heel from the heel 0 amp.

While the holddown clamp 212 has been described and illustrated as part of the machine. it has been found that such a clamp is not an essential element in the operation of the machine since the crease plates may be constructed to resist the upward pressure of the post 120 and to hold the shoe in position to have its heel-seat fitted for the reception of the heel.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
